I want to use Aris 9.8 Connectserver on a 2 node Windows environment, not for high availability purposes, but for horizontal scale out. We prefer some smaller servers instead of 1 big server. Some questions:
Thx for your reply.
Do I understand your reply well that a multi node deployment is much complexer to manage than a single node deployment?
Yes, you are right. The higher complexity is the price you pay for the advantage to scale an ARIS installation across several computers, e.g., each with a low or medium hardware sizing, instead of having ARIS installed only one computer with lots of hardware for delivering the same performance.
Not to mention that fail-over or high availability isn't of course out of scope when there is only one computer. E.g. if the Business Server runs on 3 nodes/computers, one could simply fail without data loss or an interruption at the client side.

In case of Aris Connect server in a multi node environment:
1) Yes, I heard about projects where HW based load balancing was used. Please contact your Software AG sales representative to request for implementation services.
2) ARIS uses inside TomEE for serveral apps/services, but HA is realized between ARIS apps by redundancy and sharing the work load.

we are trying 2node multi connect servers
cpu utilization and memory its good and RW to database both connect servers write to db
If you have any custom code it gets complicated to deploy on all serves etc
Abs , apg , cloudsearch etc can be configured in whatever servers you want and horizontally scale

i dis-agree on hiring softwareag consultanys
product should give detailed manuals for this distribututed arch
a client can depend on software ag pro services for ever
Its possible to split all runnables to each node, but the ARIS will not behave like a multi node high availability enviromnet . But its helpful if you have limited HW resources. (also works with ARIS9)
Node n1 - 4 installed runnables.

In case of multinode installation you will need replicate of all runnables and to do addional configuration of zookeeprs and elasticsearchs. So you will need at least 3 nodes/computers.

Dear Nico,
ARIS' cloud architecture opens up several dimensions to scale up with the customer's needs, e.g., larger number of users, broader product adoption, higher performance, added failover or high availability etc.
These various adoptions can't be delivered by standardized setups, which are meant to support a fixed installation scenario. Our server setups are meant for single node installations and can update only such.
A multi node installation requires manual software deployment/provisioning as well as updating such installations manually.
The knowledge to deploy ARIS on a multi node environment can't be read in a manual, but must be taught in the 3-days training ARIS Server Installation, offered by Software AG Global Education Services.
As you probably know, instead of acquire all that knowledge, the alternative is hiring Software AG Global Consulting Service or its implementation partners.
Cheers
Rune
